It is possible to enable the analog output permanently (it will not be switched off even if the magnetic field is out of range).

To enable this feature an OTP bit in the factory setting must be set. The corresponding bit is FS6. See application note

AS5040-20 (Extended features of OTP programming) for further details. The application note is available for download at the

austriamicrosystems website.

The analog and digital outputs will have the following conditions:

Status

DAC Output Voltage

Serial Digital Output

normal operation

10% - 90% Vref 1)

#0 - #1023 (0°-360°),

MagRngn = 1

magnetic field out of range

< 10% Vref 1),

DAC output is switched to

(this feature may be disabled

in OTP; see text)

#0 - #1023 (0°-360°)

out of range is signaled in status

bits:

MagInc=MagDec=LIN=1,

MagRngn= 0

broken positive power supply

(VOUT pull down resistor at receiving side)

< 10% VDD 2)

broken power supply ground

(VOUT pull down resistor at receiving side)

< 10% VDD 2)

broken positive power supply

(VOUT pull up resistor at receiving side)

> 90% VDD 2)

broken power supply ground

(VOUT pull up resistor at receiving side)

> 90% VDD 2)

The serial data bits read by the

serial interface will be either all

“0”-s or all “1”-s, indicating a non-

valid output

Notes:

Vref = internal: ½ * VDD5V (pin #16) or external: VDACref (pin#9), depending on Ref_extEN bit in OTP (0=int., 1=ext.)

VDD = positive supply voltage at receiving side (3.0 – 5.5V)
